HERMAN F. HASSLER, OF HECLA, SOUTH DAKOTA.

SPECIFICATION forming part of Letters Patent No. 745,057, dated November 24, 1903.

Application filed April 27, 1908. Serial No. 154,476. (No model.)

To all whom it may concern:

Be it known that I, HERMAN F. HASSLER, a citizen of the United States, and a resident of Hecla, in the county of Brown and State of South Dakota, have invented a new and Improved Governor for Centrifugal Separators, of which the following is a full, clear, and exact description.

This invention relates to improvements in attachments for centrifugal cream -separators, using the skimmed milk to accomplish the governing, an object being to provide a simple device by means of which the speed of the separator will be kept uniform, as it is well known that irregularities of speed cause fluctuations in the cream itself.

I will describe a governor for a centrifugal V separator embodying my invention and then point out the novel featuresiu the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is aside elevation of a governor for a centrifugal separator embodying my invention, and Fig. 2 is a plan view of a balancingbeam employed.

Referring to the drawings, 1 designates the casing of a centrifugal separator of the usual form, and removably placed on this casing is a receiver 2 for milk and cream discharged from the can 3 through a faucet 4, having a valve 5. Detachably connected to the receiver 2 is a bracket 6, having upwardly-extended posts 7, between which a beam 8 is pivoted. This beam is bifurcated at its inner end,'so that the members may pass at opposite sides of the vertical portion of the fancet 4, and these members are provided with slots 9, in which pulleys 10 are arranged, these pulleys being designed to support a float or valve 11 for controlling the outlet of the faucet. Cords or chains 12, attached to the valve, pass over the pulleys, and therefore they are held over said pulleys when the valve is drawn into close contact with the outlet of the faucet. The outer end of the beam 8 is provided with an adjustable Weight 13, and the end outward of this weight is movable between guide-posts 14-, in which a stop-block 15 is securely placed. This stop block is designed to limit the upward movement of the free end of the beam, and consequently regulate the opening between the valve 11 and the faucet. Pivoted to a post 16 on the end of the bracket 6 is a lever 17, having a connection 18 at one end with the beam 8, the said connection with the beam being between the weight and the fulcrumpoint of the beam. Suspended on the other or outer end of the lever 17 is a receiver 19 for skim-milk discharged from the separator through a spout 20. This skim-milk receiver preferably has aconical bottom, as shown, and at the apex of the bottom is avalve-controlled outlet 21. By manipulating the valve the outfiow of skim-milk may be regulated.

Through the guide-posts 1 1 there is passed a loose pin 22 to hold the beam 8 rigidly against the stop-block, to use in starting, to separate, to regain normal speed, or to run without the governor affecting the separator.

In the operation under normal conditions or normal speed the skim-milk will flow out through the spout 20 and into the receiver 19, from which it is allowed to escape through outlet 21. Should the speed of the separator decrease or fall below the desired point, a decreased amount of skim-milk will be forced out, consequently causing a less amount to pass into the receiver 19, and the weight of this decreased amount of skim-milk will operate the lever 17 and the beam 8 to close the valve 12, thereby shutting off the flow of milk and cream. The operator must then proceed the same as in starting, which may be accomplished in either of the following manners: First, which is recommended, the loose pin 22 is inserted in the guide-posts 14 to hold the balance rigid until normal speed is acquired; second, by closing the outlet 21 until the weight of the milk in the receiver 19 again balances the beam 8.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a centrifugal separator and a container for milk having a fancet, of a valve movable in the outlet end of said faucet, a beam carrying said valve, an adjustable Weight on the beam, a lover, a connection between said lever and one end of the beam, a receiver suspended from the other end of the lever, and a spout leading from the separator to said receiver.

2. The combination with a centrifugal cream-separator and a milk-container having a faucet, of a valve for said faucet, and means actuated by the weight of milk discharged from the separator for moving said valve to open position.

3. The combination with a centrifugal cream-separator and a container for milk having a faucet, of a pivoted beam having a bifurcated end provided with slots, pulleys in said slots, a valve for the faucet, cords attached to the valve and passing over said pulleys, a weight adjustable on the beam, a lever, a connection between one end of said lever and the beam, a skim-milk receiver suspended trom the other end of said lever and having a valve-controlled outlet, and a spout leading from the separator to said receiver.

4. The combination with a centrifugal cream-separator and a milk-container having a faucet, of a bracket removably supported on the separator, a beam having swinging connection with the bracket, a valve carried by said beam for controlling the outlet of the faucet, a weight on the beam, a guide for the free end of the beam, a block secured in said guide, a lever mounted to swing on the bracket, a connection between one end of said lever and said beam between the weight on said beam and the pivotal point, a receiver suspended from the other end of said lever and having a conical bottom provided with a valve-controlled outlet, and a spout leading from the separator to said receiver.

In testimony whereof I have signed my name to this specifiction in the presence of two subscribing witnesses.
